6 Claims. (Cl. 20-42) This invention relates to a multiple windowconstruction of the type including a plurality of vertically disposedsashes swingable about horizontal axes from closed to opened positionsand vice versa.

The application of Russell S. Strand entitled Multiple WindowConstruction, Serial No. 132,250, tiled December l0, 1949, which is nowabandoned discloses such a construction wherein the lower sash isutilized as an operator to open and close the upper sashes. The hardware includes channel-shaped tracks reciprocably disposed in runways inthe side of the window frame and receiving shoes for the sashes, theshoes for the upper sashes being adjustably secured to the tracks, andthe shoes for the lower sash being slidably disposed within the tracksand adapted to be detachably latched to the tracks. When applying thehardware to ythe sashes and the frame, to mount the sashes within theframe, considerable adjustment of the shoes for the upper sashes isusually required in order to assure proper closure of the upper sasheswhen the lower sash is closed. This is a time consuming operation and,furthermore, even when proper adjustment is attained, improper operationof the window can result because of subsequent warping of the sashes.

A main object of the invention is to provide an improved windowconstruction in which the shoes for the upper sashes are so constructedas to apply a closing force to the upper sashes, independently of themovement imparted to the sashes by the movement of the tracks, wherebythe time consuming adjustments oflthe upper shoes normally heretoforerequired is eliminated or substantially reduced, and proper operation ofthe sashes is assured even though the sashes warp subsequent to theirbeing mounted in the window frame.

Various other objects of the present invention will be apparent from thefollowing description taken in connection with the accompanyingdrawings, wherein:

Fig. 1 is a longitudinal vertical mid-sectional view in side elevationthrough a window embodying the concepts of the present invention.

Fig. 2 is a view similar to Fig. 1, but showing the sashes as havingbeen moved to their opened positions.

Fig. 3 is a horizontal fragmentary sectional view taken along line 3-3of Fig. 1.

Fig. 4 is an enlarged fragmentary side elevational view, partly brokenaway, of part of the hardware disclosed in Fig. 1, with the wedge beingshown in place.

Fig. 5 is a View similar to Fig. 4 showing parts after removal of thewedge and showing a partial upward travel of the shoe holder.

Fig. 6 is a sectional view taken along line 6-6 of Fig. 5.

Fig. 7 is a sectional view taken along line 7- 7 of Fig. 5.

Referring to the accompanying drawings wherein simi lar referencecharacters designate similar parts through out, there is disclosed awindow frame 9 having swingably mounted therein a lower sash 11 and oneor more Vice l to the tracks 19 in a manner to be presently describedand are given the reference numeral 21, whereas the shoes for the lowersash are slidably disposed within the tracks and are given the referencenumeral 23. Lower shoes 23 are adapted to be releasably latched totracks 19 by latch mechanism 25 of conventional construction, for

" instance, such as disclosed in the patent to Russell S.

Strand, No. 2,598,619.

The construction of an upper shoe is best shown in Figs. 3 through 7,where it is apparent there is included a channel-shaped shoe holder 27fitting within the assoeiated track 19 and retained therewithin by lips19a.

Fitting within holder 27 and also retained by lips 19a is the shoeproper, which comprises two pieces, an upper member 29 and a lowermember 31, the latter being adjustably secured to the track by a washer33 and a screw 35, see Fig. 3. Upper shoe member 29 is spring-biasedinto engagement with lips 19a by an L-shaped spring 39 having a convexleg compressed between said member (specifically between the riveted endof pivot. 18) and,

r.; sashes in order that the upper sashes will close tight when thelower sash is closed. These adjustment operations consume time thatcould be utilized in installing other sashes, and the adjustment time isincreased when the workmen are unfamiliar with the hardware, as is 1frequently the case. This adjustment time obviously increases theexpense of installing sashes in a window frame, and furthermore if theworkmen have a tendency to be careless, the upper sashes are likely notto tit properly.

With the upper shoe construction of the present invention, the wedges 43can be removed after the lower sash has been properly adjusted (such asset out in the application to Arthur H. Sonie, entitled Window StructureHardware, Serial No. 139,983, tiled January 23, 1950, now abandoned), toallow holders 27, under the influence of the expansion springs 41, tomove upwardly to apply a closing force to the upper sashes independentof movement of tracks 19. That is, the upper sash is yieldably disposedin a position angularly leading the lower sash, with reference toclosing movement of the sashes, so that when the lower sash is closedthe upper sash is yieldingly forced against the frame by springs 41.This application of closing forces assures that the upper sashes willclose properly when the lower sash is closed, and eliminates thetime-consuming adjustments of the upper shoes which have been heretoforenecessary. It will be apparent that the above construction will alsocompensate for warping of the sashes after they have been mounted inplace to allow proper operation thereof without binding of the tracks intheir runways.

While I have shown the preferred form of my inven- Patented May l0,1955I tion, it is to be understood that various changes may be made inits construction by those skilled in the art with out departing from thespirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. A device of the class described, comprising a window frame havingvertical slides mounted for reciprocal movement along the inner opposedside faces of. said frame, a pair of superposed sashes swingably mountedin the frame, means articulately connecting the sashes to the slideswhereby movement of the lower sash is transmitted to the upper sash tocause similar movement of the sashes upon operation of the lower sash,said means including for the upper sash a pair of shoes disposed one oneither side of and pivotally connected to the upper sash and slidablealong the slides, and spring means connected between each of said shoesand each of said slides urging the shoes upwardly relative to saidslides whereby the upper sash will slightly lead, with reference toclosing movement thereof, the angular position of the lower sash.
